1- Always wear extra eye protection. Safety goggles over eyeglasses is not enough. How those little hot sparky things got by the goggles and my glasses I don't know, but from here on out it's safety glasses, safety goggles and a full face shield. Those little hot sparky things go everywhere.
2- Always provide proper support for the work piece. A shaky sawhorse is not good. when the hot sparky things start flying and the sawhorse start shaking BAD things can happen.
3-And last but not least, always cover all exposed skin. Tennis shoes and a loose fitting pair of shorts is NOT proper attire for cutting angle iron. Did I mention that those little hot sparky things go EVERYWHERE?
I need to rethink this project, if Dominic can use 2X4's to support his ballast box why can't I?
I think I will return the uninjured angle iron to HD and buy some 2x4's.
I hate those little hot sparky things.
